If a rectangular pyramid has the same height and base as a rectangular prism, which statement explains how the volume of the pyramid can be determined?\
1) The volume of the pyramid is one-half the volume of the prism.
2)The volume of the pyramid is one-third the volume of the prism.
3)The volume of the pyramid is one-fourth the volume of the prism.
4)The volume of the pyramid is the same as the volume of the prism.
Answer:
The correct answer is "The volume of the pyramid is one-third the volume of the prism".
Step-by-step explanation:
The formula for the volume of a rectangular prism is [tex]lwh[/tex], where [tex]l[/tex] represents length, [tex]w[/tex] represents width, and [tex]h[/tex] represents height. The formula for the volume of a rectangular pyramid is [tex]\frac{lwh}{3}[/tex], where [tex]l[/tex] represents length, [tex]w[/tex] represents width, and [tex]h[/tex] represents height. Since the base and height of the rectangular pyramid is the same as the rectangular prism, that means the volume of the pyramid is one-third of the volume of the rectangular prism.

Consecutive even integer word problem help please!!
Answer:
Width: 16 in., Length: 18 in.
Step-by-step explanation:
Consecute even/odd problems seem a bit weird at first.
You choose a variable to represent the first integer, say n . Assume it's even (no symbolic way to tell!). If n is even, then the next consecutive integer is n + 2. You add two because you want to skip one integer.
Width: n
Length: n + 2
Area is length multiplied by width, so
[tex]n(n+2)=224\\\\n^2+2n=224\\\\n^2+2n-224=0\\\\(n+14)(n-16)=0\\\\n+14=0 \text{ or } n-16=0\\\\n=-14 \text{ or }n=16[/tex]
The negative solution makes no sense, so use n = 16
Width: 16
Length: 18

5.3x - 9 + 7.6x simplify pls
Answer:
12.9x-9
Step-by-step explanation:
add 5.3x and 7.6x
Answer:
12.9x-9
Step-by-step explanation:
First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self because there's no other like terms.
More examples -
5.3x+−9+7.6x
Combine Like Terms:
=5.3x+−9+7.6x
=(5.3x+7.6x)+(−9)
=12.9x+−
The area of a rectangle is 81cm^2 what are the dimensions if the perimeter is minimum. What is the value of these minimum perimeter?
Answer:
The perimeter is 36 cm
Step-by-step explanation:
Given;
area of the rectangle, A = 81 cm²
let the Length, = L
let the breadth = b
Perimeter, P = 2L + 2b
Area, A = Lb = 81
[tex]L = \frac{81}{b} \\\\P = 2(\frac{81}{b} ) \ + \ 2b\\\\P = \frac{162}{b} \ + \ 2b\\\\P = 162(b^{-1}) \ + \ 2b\\\\minimize \ the \ perimeter \ to \ obtain \ the \ critical \ points;\\\\P' = -162 (b^{-2}) \ + \ 2\\\\P' = \frac{-162}{b^2} \ + \ 2\\\\P' = \frac{-162 \ + \ 2b^2}{b^2} \\\\at \ critical \ points; P' = 0\\\\\frac{-162 \ + \ 2b^2}{b^2} = 0\\\\-162 \ + \ 2b^2 = 0\\\\2b^2 = 162\\\\b^2 = 81\\\\b = +/- \ \sqrt{81} \\\\b = +/- \ \ 9\\\\[/tex]
[tex]since \ the \ breadth \ will \ be \ positive \ ; b = 9 \ cm[/tex]
L = 81/9
L = 9 cm
The perimeter = 2 (L + b)
= 2 (9 + 9)
= 2(18)
= 36 cm
One angle of an isosceles triangle measures 138°. Which other angles could be in that isosceles triangle?
Answer:
2 21 degree angles
Step-by-step explanation:
An isosoles triangle has two congruent angles and every triangle's sum of interior angles equals 180 degrees. 138*2>180, so the 138 degree angle cannot be congruent to any of the other angles. Therefore:
180=138+2x
42=2x
21 degrees=x
make b the subject of the formula a=\sqrt(b+6)
Making 'b' the subject of formula gives b = a² - 6
How to determine the subject of formulaIt is important to note that the subject of formula is described as a variable that is made up to stand alone in an equation.
The subject of formula is the variable that is worked out on on side of the equation sign.
From the information given, we have the equation;
a = [tex]\sqrt{(b + 6)}[/tex]
To make 'b' the subject of formula, we take the following steps;
Find the square of both sides, we get;
a² = [tex](\sqrt{(b + 6)} ^2[/tex]
Cancel out the square, we get;
b + 6 = a²
collect the other terms on one end of the equation, we have;
b = a² - 6
Hence, the equation is b = a² - 6

Which expression is not equal to the expression shown?
3³ ÷ 3⁻⁴
____________________Solution :-Given Information :-Equation 1 ( question )➢ 3³ ÷ 3⁻⁴Equation 2 ( option 1 )➢ 3⁻³ ÷ 3⁴Equation 3 ( option 2 )➢ 3 × 3⁶Equation 4 ( option 3 )➢ 3⁷ ÷ 3⁰Equation 5 ( option 4 )➢ 3³ × 3⁴To Find :-Which expression is not equal to the expression shown. Calculation :-Let's first solve all the equations and then check which equation is not equal to equation given in question.
Solving Equation 1 ( question ) :-⇒ 3³ ÷ 3⁻⁴ = 3³⁻⁽⁻⁴⁾
⇒ 3³⁺⁴ = 3⁷ = 2,187
Solving Equation 2 ( option 1 ) :-⇒ 3⁻³ ÷ 3⁴ = 3⁻³⁻⁴
⇒ 3⁻⁷ = 0.000457
Solving Equation 3 ( option 2 ) :-⇒ 3 × 3⁶ = 3⁷
⇒ 3⁷ = 2,187
Solving Equation 4 ( option 3 ) :-⇒ 3⁷ ÷ 3⁰ = 3⁷ ÷ 1
⇒ 3⁷ ÷ 1 = 2,187
Solving Equation 5 ( option 4 ) :-⇒ 3³ × 3⁴ = 3³⁺⁴
⇒ 3⁷ = 2,187
From the calculation of above equations, We have found that only Equation 2 ( option 1 ) 3⁻³ ÷ 3⁴ is not equal to Equation 1 ( question ) 3³ ÷ 3⁻⁴
Therefore, 3⁻³ ÷ 3⁴ ≠ 3³ ÷ 3⁻⁴
Hence, Option 1 is the correct answer.

An equivalent expression of (33 x 66) - 3 is 2175.
What is PEMDAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Given:
We have an expression,
(33 x 66) - 3.
Solving further by using PEMDAS,
33 x 66 = 2178
Now,
(33 x 66) - 3,
= 2178 - 3
= 2175
Therefore, the solution is 2175.

Answer:
C. (4 , 3)
Step-by-step explanation:
We are given a system of equations and are asked to find its coordinate value.
To solve, we can keep in mind that both start with y, therefore meaning that we can replace one of the y's with one of the equations.:
[tex]y=\frac{1}{4}x+2\\y=x-1[/tex]
[tex]\frac{1}{4}x+2 = x-1[/tex]
Let's try to get x alone, first subtract 2 from both sides:
[tex]\frac{1}{4}x=x-3[/tex]
Now subtract x from both sides:
[tex]-\frac{3}{4}x=-3[/tex]
Now since the denominator is 4, multiply both sides by 4:
[tex]-3x=-12[/tex]
Lastly, divide both sides by -3 to get x :
[tex]x=4[/tex]
Now that we know x is 4, we can substitute 4 for x in both equations:
[tex]y=\frac{1}4(4)+2\\y=(4)-1[/tex]
[tex]y= 3\\y= 3[/tex]
Y is equal to 3, therfore, our coordinate value is C. (4,3)

Answer:
B. AC = 22, BC = 22, AB = 44
C. AC = 30, BC = 30, AB = 60
Step-by-step explanation:
B.
[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)
[tex] \therefore AC = BC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)
[tex] \therefore 2x - 6 = x + 8[/tex]
[tex] \therefore 2x - x= 6 + 8[/tex]
[tex] \therefore x= 14[/tex]
[tex] AC = 2x-6=2(14)-6=28-6= 22[/tex]
[tex] BC= x + 8=14 + 8= 22[/tex]
AB = AC + BC = 22 + 22 = 44
C.
[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)
[tex] \therefore BC = AC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)
[tex] \therefore 7x-5=4x+10 [/tex]
[tex] \therefore 7x - 4x= 5 + 10[/tex]
[tex] \therefore 3x= 15[/tex]
[tex] \therefore x= \frac{15}{3}[/tex]
[tex] \therefore x= 5[/tex]
[tex] AC = 4x+10=4(5)+10=20+10= 30[/tex]
[tex] BC= 7x - 5=7(5)-5=35-5= 30[/tex]
AB = AC + BC = 30 + 30 = 60
